Cannot run git commands inside of devcontainer

[sgraband]

Bug Description:

I can no longer run git commands in a dev container, because the authenticy of github cannot be established.
I assume that there is some sort of local config not shared with the devcontainer.
This is probably only a symptom for me and the issue affects much more tools and use cases.

Error message when running git commands:

The authenticity of host 'github.com (140.82.121.3)' can't be established.

This definately already worked before so it's probably a regression.

Steps to Reproduce:

1. Open a Devcontainer
2. Open a terminal
3. Run a git command and notice that the error above is there.

Additional Information

• Operating System: Ubuntu 22.04
• Theia Version: Theia 1.58.0

@jonah-iden Do you have an idea what might be the problem here?

[jonah-iden]

weird, looks on the first glance like some ssh key issue. Are you using git via ssh? Then it may be because its using the git from inside the container which does not have your key. Or in general not the same list of known hosts as outside

[sgraband]

Yes exactly. I am using Git via SSH and it seems like the known hosts are not available in the container and the key seems to not be available as well.

ok then that sounds more like a missing feature. Not sure how vscode handles this
